Abstract A significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. This research presents a straightforward approach for processing output of the HEC-RAS hydraulic model, to enable two- and three dimensional f...

Supplementary data Data processing 1. Topographic data Because the SRTM data are not continuous, we filled minor holes of a few pixels by interpolation and filled larger holes with 90-m elevation-adjusted Digital Terrain Elevation Data (DTED). For the remaining regions with missing topographic information, we used digital elevation models (DEMs) created from stereo-views of the Advanced Spacebo...

Compared to laser radar systems based on the conventional discrete echo approach, direct detection laser radar systems with echo signal digitization and subsequent full-waveform analysis like the RIEGL LMS-Q560 provide valuable additional information on the target’s properties. This additional information can be used in the course of the mandatory processing task of classifying the measurement ...
